Online hate speech could be contained like a computer virus, say Cambridge researchers

Credit: Stefanie Ullman The spread of hate speech via social media could be tackled using the same “quarantine” approach deployed to combat malicious software, according to University of Cambridge researchers. Definitions of hate speech vary depending on nation, law and platform, and just blocking keywords is ineffectual: graphic descriptions of violence need not contain obvious ethnic slurs to constitute racist death threats, for example. As such, hate speech is difficult

Millions with swallowing problems could be helped through new wearable device

Uranium chemistry and geological disposal of radioactive waste

New insights using the diamond light Credit: Diamond Light Source A new paper to be published on 16 December provides a significant new insight into our understanding of uranium biogeochemistry and could help with the UK’s nuclear legacy. Conducted by a team of researchers from the University of Manchester, Diamond Light Source and Radioactive Waste Management, their work shows for the first time how uranium forms a uranium-sulfur complex under

Dartmouth study finds conscious visual perception occurs outside the visual system

Credit: Figure by Sirui Liu and Patrick Cavanagh. A Dartmouth study finds that the conscious perception of visual location occurs in the frontal lobes of the brain, rather than in the visual system in the back of the brain. The findings are published in Current Biology. The results are significant given the ongoing debate among neuroscientists on what consciousness is and where it happens in the brain. “Our study provides

Mitochondria are the ‘canary in the coal mine’ for cellular stress

Finding by Salk researchers helps explain how some cancers resist chemotherapy Credit: Salk Institute/Waitt Advanced Biophotonics Center LA JOLLA–(December 13, 2019) Mitochondria, tiny structures present in most cells, are known for their energy-generating machinery. Now, Salk researchers have discovered a new function of mitochondria: they set off molecular alarms when cells are exposed to stress or chemicals that can damage DNA, such as chemotherapy. The results, published online in Nature

PHOENIX – Women with bacterial vaginosis exhibit elevated levels of the pro-inflammatory protein, IL-36y, according to a new collaborative study led by the University of Arizona College of Medicine-Phoenix. Bacterial vaginosis (BV) is the most common bacterial infection in

A guidebook for local governments and CBOs to support elderly people to take out the trash

Credit: NIES One of the issues related to waste management in aging society is helping elderly people who find it difficult to take out the trash. In the face of the aging of society and increasing numbers of nuclear (one- and two-generation) family households, more and more elderly people are in need of support. In Japan, many local governments have introduced a program to support elderly people taking out their
